Biaxial testing machine H.11 series

torsionfatigueautomatic

Servohydraulic dynamic biaxial testing machines of the H.11 series are designed to perform low and high cycle fatigue tests of fracture toughness, crack propagation, etc. This series of machines is characterized by high rigidity of the frame with long life, mechanical resistance and self-absorption of resonances. The wide range of Hydraulic units allows you to dynamically load samples up to Fmax. 250kN and frequency up to 50 Hz. • Robust vertical stand design with extremely high lateral rigidity, resonant and mechanical resistance in dynamic mode for each test axis of the machine. • Powerful compact hydraulic units of the HAD series with low noise level designed for fatigue tests with water cooling • Diagnostics of the hydraulic unit HALT 18 controlled by TOUCH LCD SIEMENS at standard. • Control of individual axes by proportional or servo valve in power and position loop. • Complete test evaluation and control is provided by Test & Motion material testing software – DYNPACK. • The H.11 series machines comply with all the above-mentioned EC directives on machinery and equipment and work in accordance with the new safety functions according to EN ISO 13850-SIL 1/PL. • Combined torsion load cells located on the piston rod operating in the accuracy class according to EN ISO 7500-1, ASTM E4 with the possibility of linearization. • The compact measuring and control electronics of the EDCi Control – BIAXIAL series are preferably designed to handle this top application. Synchronization of all measuring and control channels with sampling frequency 10kHz in real time…. Analog signal resolution level ± 250,000 divisions (20 ms).
